      <description>&lt;p&gt;The catalog behind the studio twin, the one I&amp;rsquo;ll fill by &lt;a href=&#34;https://ttvl.co/research/ambient-computing/catalog-by-photo/&#34;&gt;photographing drawers&lt;/a&gt;, starts as a folder of plain files rather than a database:&lt;/p&gt;
&lt;div class=&#34;sheet&#34; data-lang=&#34;text&#34;&gt;
&lt;div class=&#34;sheet__kicker&#34;&gt;inventory/&lt;/div&gt;
&lt;div class=&#34;sheet__scroll&#34;&gt;
&lt;pre&gt;&lt;code&gt;places.json       &lt;span class=&#34;c&#34;&gt;# generated from the 3D model, one record per slot&lt;/span&gt;
movables.json     &lt;span class=&#34;c&#34;&gt;# boxes and carts, and where each one is&lt;/span&gt;
items.jsonl       &lt;span class=&#34;c&#34;&gt;# one line per thing: name, English and Italian aliases, category, place, count, last seen&lt;/span&gt;
captures/
  inbox/          &lt;span class=&#34;c&#34;&gt;# new photos&lt;/span&gt;
  2026-10-02/     &lt;span class=&#34;c&#34;&gt;# photos and what Claude read, before confirmation&lt;/span&gt;&lt;/code&gt;&lt;/pre&gt;
&lt;/div&gt;
&lt;/div&gt;
&lt;p&gt;The places come out of the model build, so they never drift from the 3D model. Each thing is one line, so every change is a readable diff. Claude reads a photo and edits the files; I review the change as a git diff and confirm it, the same way I review code. Nothing needs a server until the phone app does.&lt;/p&gt;
